Axial Stress Thick Wall Cylinder Equations and Calculator

If the pressure (p_i) is confined at the ends, an axial (longitudinal) stress (σ_a) is also developed. It is assumed that the external pressure p_o is zero. The geometry and stresses, including the tangential stress (σ_t), are shown in Figure 1

Using the geometry of figure 1 axial stress (σ_a) is given by:

Axial Stress Formula:

σ_t = ( p_ir²_i ) / ( r²_o - r²_i )

p_i = internal pressure (psi, MPa),
r_i = inside radius (in, m),
r_o = external radius (in, m)
